core:Add a script that displays async ...(#868672)

Adding a fn_db_get_async_tasks function to the database.

Displays DC id , DC name, SPM Host id , SPM Host name and number of
async tasks awaiting.

Example:

ovirt=# select  * from fn_db_get_async_tasks();
-[ RECORD 1 ]-+-------------------------------------
dc_id         | 64600e6a-ef8b-11e1-838c-0fc062f03f3a
dc_name       | Default
spm_host_id   | b021eada-ef8b-11e1-8e97-579ccb995b3c
spm_host_name | pluto-vdsa
task_count    | 2

The functions does the following steps to gather the required
information:

1) create a record type with DC name, DC id, SPM host id, SPM host name,
count

2) get all distinct DC ids from async_tasks table

3) Run a cursor for each result in 2)

   a) get DC name
   b) get SPM Host id & name if available
   c) get count of tasks

   return current record

4) return set of generated records

regarding the required compensation information:

use the following query:
select command_type, entity type from business_entity_snapshot

please note:
command_type is a fully qualified name , consider to take only its
suffix.
entity type is a string identifying the entity (like vm_static etc.)
